Recovery of tailings from the vanadium extraction process

05-09-2018  Approximately 90% and 95% of vanadium and chromium recoveries in magnetic fraction can be achieved for the magnetic separation step. The content of vanadium and chromium significantly increased to 3.00% and 2.20% in magnetic fraction, respectively, while dramatically decreased to 0.44% and 0.20% in the non-magnetic part.

Recovery of iron from vanadium tailings with coal-based

A technique with coal-based direct reduction followed by magnetic separation is presented in this study for recovering and reusing iron otherwise wasted in vanadium tailings. Process parameters such as usage of additives, tailings/reductant/additives ratio, reduction temperature and time, as well as particle size were experimentally determined.
